Synthesis and Luminescent Properties of Lanthanide(III)-Chelated ComplexesBased on Dendrimeric Benzoquinoxaline Derivatives |
| 초록 |
A series of novel lanthanide(III) complexes based on dendritic benzoquinoxaline ligands was designed and synthesized to enhance the luminescence intensity of Er3+ ions for photonic applications. The benzoquinoxaline ligand was used as photon antenna for the efficient light harvesting effect by improving the low quantum yield and molar-extinction coefficient of the aryl-ether dendron. The benzoquinoxaline ligands have been also designed and synthesized in order to provide enough coordination sites for the formation of stable Er(III)-chelated complexes. Er3+-cored supramolecular complexes based on dendritic benzoquinoxaline ligands exhibit strong near-IR emission band at 1530nm through energy transfer from the excited states of the benzoquinoxaline ligands to the Er3+ ion. |
